To help people assess Islam, this site presents core Islamic texts. So readers can verify that we are correctly presenting these, each text includes reference links. The links lead in some cases to passages in a Qur'an-and-Hadith database at a university, in other cases to the earliest Muslim biography of Muhammad. When citing the Hadith, we cite only the canonical collections, whose reports most Muslim scholars of Islam deem authentic.

Muhammad says, "Fight everyone in the way of God and kill those who disbelieve in God."
